Thanks for the template. But I am a bit confused about how to apply the
implementation.
The code in my doc is like this:
<equation><title>Z-R Relation</title>
<xi:include xmlns:xi="http://www.w3.org/2001/XInclude";
href="e5-math-zr-basic.xml"/>
</equation>
and the included file is:
<?xml version="1.0" encoding="utf-16"?>
<!--
File: e5-math-zr-basic.xml
Date : Sept 15, 2007
;-->
<!DOCTYPE mml:math PUBLIC "-//W3C//DTD MathML 2.0//EN"
"http://www.w3.org/TR/MathML2/dtd/mathml2.dtd"; [
<!ENTITY % MATHML.prefixed "INCLUDE">
<!ENTITY % MATHML.prefix "mml">
]>
<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"; id="mymath">
<mml:mrow>
<mml:mn>Z</mml:mn>
<mml:mo>=</mml:mo>
<mml:mn>a</mml:mn>
<mml:msup><mml:mi>R</mml:mi><mml:mn>b</mml:mn></mml:msup>
</mml:mrow>
</mml:math>
However, the formula shows up left aligned and I need it centered. So how do I
specify the "alignment" when using your template?
I am using SAXON and FOP 0.94.

The current stylesheets are not very sophisticated. The MathML markup gets
through to the output, but that's about it.
The following customization adds support for @align and @valign on imagedata
(the original template is in math.xsl):
<xsl:template match="mml:math"
xmlns:mml="http://www.w3.org/1998/Math/MathML";>
<xsl:choose>
<!-- * If user is using passivetex, we don't wrap the output in -->
<!-- * fo:instream-foreign-object (which passivetex doesn't support).
-->
<xsl:when test="not($passivetex.extensions = 0)">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:when>
<xsl:otherwise>
<fo:instream-foreign-object>
<!-- Support for two imagedata attributes -->
<xsl:if test="../@align">
<xsl:attribute name="text-align">
<xsl:value-of select="../@align"/>
</xsl:attribute>
</xsl:if>
<xsl:if test="../@valign">
<xsl:attribute name="display-align">
<xsl:choose>
<xsl:when test="../@valign = 'top'">before</xsl:when>
<xsl:when test="../@valign = 'middle'">center</xsl:when>
<xsl:when test="../@valign = 'bottom'">after</xsl:when>
<xsl:otherwise>auto</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
</xsl:if>
<!-- End of customization -->
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</fo:instream-foreign-object>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I'm not sure if this is the way to go in the long run. I guess that it would
be better if the process.image template in graphics.xsl could be reworked so
that it also supports imagedata attributes for MathML (and SVG).
